The telescopic fist is the first power that Rayman is granted by Betilla in the original Rayman game in Pink Plant Woods. It is his most widely used power, and with it, he can hurl a fist that defeats any enemies that are in his way. Another power, the grappling fist, allows Rayman's fist to grab objects such as extra lives and flying rings. It can be powered up by picking up gold fists, which doubles the fist power, and speed fists which makes him throw it faster. Picking up more speed fists, up to three, will further increase the speed. Rayman can also increase the power of his punches by either charging the fist or punching while jumping.

The telescopic fist returns in Rayman 3. Rayman can shoot it laterally by strafing around enemies. The fist can be upgraded temporarily by the Laser-Washing Powder cans some Hoodlums leave behind. Using his fist isn't his only means of attack in the game. Rayman can also kick his opponents if he is close enough.

The telescopic fist can be used offensively against most enemies in the game, barring the Knaaren who do not take damage against it and can only be evaded. The stilts of the Stumbleboom are also resistant to Rayman's telescopic fist, but can be destroyed if the Vortex power-up is active.

Rayman starts out the game without his fists due to Globox having accidentally pulled them off before escaping.

Rayman uses his telescopic fist in the Game Boy Advance version of Rayman 3 in a similar manner to how it was used in the original Rayman game, with him being able to charge his fists for stronger attacks or just throw them normally. Throughout the game he will receive several upgrades for his fists, such as being able to throw both at once, grab Purple Lums and charge the fists for even stronger attacks.

Rayman begins Rayman Origins with only the ability to jump on enemies to defeat them, this is quickly rectified as Rayman and his friends rescue Betilla in It's a Jungle Out There..., who then gives the heroes the ability to attack. Unlike past titles, where the telescopic fist was Rayman's primary means of attack, Rayman is now able to perform a variety of attacks and combos. The telescopic fist remains accessible to Rayman by holding down the attack button, and releasing, as it behaved in past titles. Other heroes also have attacks that are functionally similar, but aesthetically different, Globox attacks using slaps, while Teensies attack using magic.

The attack power is retained in Rayman Legends, all previous characters use the same attacks, barring the ground kick move, which is changed to a ground slam move.
